Be aware that the I/O pins on the Teensy 4 .1 are NOT 5V compatible and MUST operate at 3.3V. Putting 5V on any Teensy pin will likely KILL that pin and potentially the Teensy as well. It might help if you stated which Wiegand rfid you are using...

You need to allow access to here.

You’ve received a lot of useful help and have expressed little gratitude. Hope you find your solution and give something back.

You could post it here.

Above translates to: Hello, I want to buy it, how can I buy it?

Have a look at VisualMicro. It works with Visual Studio and also offers The plug-in allows you to use breakpoints for step-by-step execution, monitor execution time between breakpoints, and set conditional breakpoints based on data or hit count...

It can be used with Atmel Studio.

I know what you are saying but Visual Studio Community is FREE and Visual Micro can be used for 45 days before you have to buy it and then only US$19 a year (US$1.58 a MONTH). $1.58 a Month for hassle free development.

You move fast, Steve_AU! Pleased to hear that you will be checking out the evaluation board. I look forward to hearing more about your experience with the setup, and hope you find it helpful. I agree that these devices in the current 600MHz+...

Yes.

Below is a connection diagram for you. What follows is an explanation of connections: VDD refers to the voltage level for a side be it side 1 (A) or side 2 (B). In the diagram below Side 1 (A) has been chosen for the Teensy and Side 2 (B) for the...

Teensy LC to T4.1 is ok, they are both 3.3V. For nano to Teensy LC or 4.1 use an Adum1201 for level shifting (5V to 3.3V). The Adum1201 is designed for Serial Comms level shifting. It is possible to buy ready made Adum1201 modules. See here and here.

I use RV-3028-C7 on my boards/systems. The standby current is quoted in nA with an accuracy of +/-1ppm.

You have not said how you wish to use the output. It's difficult to make recommendations without that data.

So what is your question?

It is.

When posting your code, please post it using the </> button. This maintains the code formatting and makes it easier for others to understand your code and be able to help. Unfortunately I have not used the CAN bus so I am unable to help you...

If you connected a pin supplying 5V to the Teensy you at the very least probably destroyed that pin. It is possible that you did further damage to the Teensy. Other than the 5V input pin you CANNOT put 5V on any other pin without damaging the...

Just a thought, how about debugging on the Pico, then compile for Teensy. I know I/O etc is likely to be different but I would have thought the core software would have been the same. You could use something like: #define pico //#define...

Ok, consider adding a 3d printed or other support. Such a support would be simple to design/print.

Could we see your code.

There is no reason why the enclosure cannot be modified to support the underside of the PCB (I assume you are 3d printing). You would have to leave a grove for clearance where the pins come through the underside of the PCB. That's what I do on...

One thing to be careful with when cutting the track is to make sure that you do NOT cut too deep. This is a multi layer (5 I believe) board and it's possible that you have severed tracks underneath the top layer. The track to be cut is on the...

To clean off any solder flux that might be causing a problem.

If you have not done so try cleaning the board with a tooth brush and IPA (alcohol).

That's the 3V regulator. If it's getting hot it might be an indication that there is a short somewhere. I suggest looking for errant solder spikes on your connections which might be pulling the 3V down.

In usb_desc.h used on Teensy 4, the define JOYSTICK_SIZE appears in 4 places. Did you edit the correct ones? Or all of 4 of them? As a quick sanity test, try editing them one at a time into something wrong, like a word rather than a number...

The ones I listed above are £0.39 (50c) each. I don't think you will beat that on price. See below.

Perhaps you should be looking at the lockable version. Can only be re-programmed if you have the correct key (software key).

Why? The Arduino IDE has the ability to just compile the code or compile and program.

Probably supply and demand. Not too much demand so have to hold stock longer...money tied up longer, not producing an income.

I've used this sort of regulator quite successfully in the past to do what you want to do. It's a complete solution on a mini-board, has all the Rs and Cs etc.

I reckon its on line 42 - its the answer to life, the universe and everything. Apparently...

If you were going to change I would recommend Visual Studio (Community (free) Edition) with Visual Micro. You get all the standardisation of using Arduino IDE with the modern Visual Studio editor. Platform IO gives too many problems..tried it...

Cut the track and FEED THE 5V input.

Yes, no problems.

Make your setup something like:- void setup() { Serial.begin(9600); /* check for CrashReport stored from previous run */ if (CrashReport) { /* print info (hope Serial Monitor windows is open) */ Serial.print(CrashReport); } } See...

Hi Arun. I have not used FlasherEx but looking at the forum I know lots of people have fount it useful. I believe you have to have the Text identifying your target in the new code. Something like Serial.print("teensy4.1"); would suffice. You just...

Have a look at VisualMicro for the Arduino IDE. You have all the benefits of Visual Studio with the Arduino "Simplicity".

Should be OK with Turned Pins on Teensy. Some here.

It is NOT a RESET button, but a PROGRAM button. You could have a small hole over the PROGRAM button and then press it with a pin.

With FlasherX. Have a look here.

Using flasherX. Have a look here as a starting point.

Presumable the same change needs to be made to ...\cores\teensy3\DMAChannel.h?

I went through the process of getting the Teensy 4 bootloader chip (IC_MKL02Z32_T4_QFN16) added to the list of parts at JLCPCB. As always you will need to buy it from PJRC and send it to JLCPCB as a consigned part. Its now JLCPCB part#...

Can you show your code. There may be something there that is making the difference. It will/may also allow others to duplicate the error to investigate.

Can you post the code? Use the "</>" button, it maintains indenting etc.

I did a Google search and came up with this.

The NCP692MN33T2G data sheet says that heat will be dissipated from the GND connection through the copper of the PCB. Paul is making you aware that this TINY voltage regulator may heat up with 100mA current flowing. This heat will have to be...
